According to the IIoT concepts it is possible to infer that CyberPhysical Production Systems (CPPS) systems are normally connected to each other, and also connected to the virtual world of global digital networks. That is why introducing the IEC-61499 standard, will allow the CPPS to implement distributed, flexible and reconfigurable controllers. All this with the aim that industries being more competitive, which are constantly taking decisions in different industrial systems gaining in complexity, this can be improved applying qualitative and quantitative methods like the Fuzzy Analytical Hierarchy Process (FAHP). For this reason, it is necessary to provide the industry with low-cost alternatives which could redirect the CPPS development to a new variety of devices. This paper proposes the development of the FBs networks needed in the control of industrial processes based on the AHP methodology, broadly used in decision making.","PeriodicalId":6522,"journal":{"name":"2017 22nd IEEE International Conference on Emerging Technologies and Factory Automation (ETFA)","volume":"7 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89067535","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To account for ambiguity and vagueness in some real-world data and preferences, in the first phase of the approach, the Fuzzy Technique for Order Preference by Similarity to Ideal Solution (fuzzy TOPSIS) method is used to obtain the overall performance and risk ratings of the suppliers with regard to a set of qualitative and quantitative criteria. In the second phase, we introduce a novel multi-objective possibilistic mixed integer linear programming model (MOPMILP) for solving an IPP planning considering conflicting goals simultaneously: maximization of the overall performance and minimization of the overall risk. Then, after converting this MOPMILP model into an equivalent crisp multi-objective mixed integer linear programming (MOMILP) model, we use the Goal Programming (GP) approach to solve this MOMILP model in order to find an efficient compromise solution (i.e. an efficient procurement production plan) for the whole SC. The proposed approach and solution methodology are validated through a numerical example.","PeriodicalId":6522,"journal":{"name":"2017 22nd IEEE International Conference on Emerging Technologies and Factory Automation (ETFA)","volume":"5 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88997336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes optimization process of the light color and intensity for inspection of active matrix organic light emitting diode (AMOLED) panels using a random-search method. The raw image acquired by a line scan camera had low luminance uniformity due to the surface condition of the AMOLED. The brightness deviation of the image was corrected to increase uniformity. The image quality after the correction was evaluated using a kind of image index, namely Tenenbaum gradient. The random-search method switched the dimming levels of the color source until a better image index was obtained. The random search was formulated for a multi-dimensional vector to be used in an arbitrary number of color sources. The random value in this study was generated using Gaussian random method, and was terminated when the size of a random vector became sufficiently smaller. The random-search method for automatic light control of AMOLED inspection showed 0.6% difference in the image index between the equal-step search and the proposed method. However the number of iterations in the proposed method was 22 but that of the combinations was 20484.","PeriodicalId":6522,"journal":{"name":"2017 22nd IEEE International Conference on Emerging Technologies and Factory Automation (ETFA)","volume":"21 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89698825","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The manipulator has to cope with a broad variety of objects with different shapes, materials and uncertain poses but at the same time it should provide reliable grasping and placement operations. Within this context, tactile sensors mounted directly on the grippers are a promising solution for monitoring the grasping process. They operate independently from light or line of sight configurations, thus offer a new object detection modality, besides optical-based systems. We receive an imprint of the grasped object with a spatial resolution according to the sensor pattern. However, in case of grippers with a flexible structure and material, this method generates spurious measurements if the gripper is deformed during a manipulation process. This effect disturbs the evaluation of the gripper's state or object position. In this paper, we develop the specification of a tailored tactile sensor configuration able to handle gripper deformations. Based on the results we present a proof-of-concept implementation.","PeriodicalId":6522,"journal":{"name":"2017 22nd IEEE International Conference on Emerging Technologies and Factory Automation (ETFA)","volume":"26 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2017-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84299497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The performance of wireless network and its Quality of Service (QoS) must thus be analyzed in order to guarantee a good QoC. The present paper proposes an analysis of QoS performance metrics for networked systems (networked robots) using an analytic model based on Markov chain theory.
